It depends on your goals. "Bodybuilding" in the sense of physique and symmetry is much less about gym time and more about rigorous diet and nutrition. I was a D1 athlete in the ACC and I couldn't even keep up with my lifting program in medical school let alone stay with a bodybuilding diet.
If competition isn't your goal, then sure you can get ripped pretty easily: again, it's just diet. However, I feel that a proper diet is extremely difficult to maintain in school simply because you're going to have an erratic schedule.
If you've never lifted before, don't jump into a bodybuilding routine. Either find someone in your class that can teach you the basic compound lifts or find a gym with people that actually train. You can try reading a book like Starting Strength, but it'll slow your progress down learning the lifts without a teacher. Your 6x/week lifting program is too much unless you're on steroids.
Sites like animalpak and t-nation are basically fronts for companies peddling products of varying utility so take their messages with a grain of salt. That's not to say that their articles are complete bunk, but they'll usually make a good point and then say "product X from BIOTEST or ANIMALPAK is AWESOME and what you really need to get huge!"
You don't need any supplements to start aside from a decent protein. Really, all you do is eat good foods, lift properly, and you'll see immediate growth.
I'll second everything here, and add that "eating properly" is often not always intuitive to beginners. Without going overboard (I say that because diet can really consume you if you're ultra-anal about it, and that's really not what a beginner needs), take a look at something like this one:
